Caution! When the phantom power is
switched on, never connect unbalanced
microphones or units with line level to
the corresponding input; otherwise, the
microphones and units may be damaged .
3) Depending on the configuration, the
power amplifiers for the speakers or
sub sequent units with line level can be
connected to the XLR jacks CH 1 to CH 6
OUT (13) and STEREO OUT (12) .
5.1 Switching on the microphone
phantom power
To be able to also operate phantom-powered
microphones, it is possible to switch on a 12 V
phantom power separately for each of the six
mono channels .
Attention! To switch on the phantom
power, the unit must be opened . This must
be done by skilled personnel only .
1) Disconnect the mains plug from the mains
socket .
2) Unscrew the housing cover .
3) For the desired channels, rearrange the
corresponding jumpers JP 101 (for channel
CH 1) to JP 601 (for channel CH 6) from
OFF to ON .
4) Tightly screw the housing cover again .
5) It is recommended to mark the input jacks
of the channels provided with phantom
power accordingly!
6 Operation
1) Prior to switching on, all output controls
(5 and 9) should be set to minimum to
prevent switching noise .
2) Switch on the unit with the POWER switch
(10) . To indicate that the unit is ready for
operation, the red LED (2) above the switch
lights up . Then switch on the connected
units .
6.1 Mixer mode
In the mixer mode (Fig . 2, page 5), a ste-
reo channel and up to six mono channels can
be mixed to a stereo output channel .
1) Disengage the selector button MIX /
SPLIT (7) for the respective channel and
engage the selector button MIXER ON (8) .
2) Turn up the control LEVEL STEREO OUT
(9) so that the mixing ratio of the con-
nected audio sourc es can be adjusted in an
optimum way .
3) Use the selector buttons LINE / MIC (4) to
match the mono channels CH 1 – CH 6 to
the sources connected . When a micro-

phone is connected, engage the selector
button; for units with line level, disengage
the button .
4) Use the controls LEVEL STEREO IN (3) and
the channel controls LEVEL CH 1 – CH 6 (5)
to adjust the volume ratio desired: Set the
audio sources to be heard at the highest
volume in such a way that the correspond-
ing LED (1) briefly lights up in red with
music peaks .
5) Use the controls PAN (6) of the mono
channels CH 1 – CH 6 to place the mono
channel signal into the stereo base as
desired .
6) Use the control LEVEL STEREO OUT (9)
to adjust the definite level of the stereo
master signal .
6.2 Splitter mode
In the splitter mode (Fig . 3, page 5), a stereo
signal can be distri buted to six mono channels
and a stereo channel . For the mono channels,
the signal parts of the stereo signal can indi-
vidually be adjusted with the PAN controls . For
the stereo output channel, no free assignment
is possible; the left input signal is as signed
to the left output signal, and the right input
signal is assigned to the right output signal .
1) Engage the selector button MIX / SPLIT (7)
for the respective channel .
2) Use the controls LEVEL STEREO IN (3) to
adjust the input level of the stereo signal
so that the LEDs (1) briefly light up in red
with music peaks .
3) For the six mono channels, adjust the
desired signal part of the stereo signal with
the PAN controls (6) .
4) Use the control LEVEL CH 1 – CH 6 (5) to
adjust the levels of the mono channels
individually .
5) Use the controls LEVEL STEREO OUTPUT
(9) to adjust the level of the stereo output
signal .
6.3 8-channel amplifier mode
In this mode (Fig . 4, page 5), the channels
operate as independent amplifiers which
supply a balanced output signal of low
impedance . The levels of the six mono chan-
nels and the stereo channel can individually
be adjusted . This level adjustment is e . g .
necessary when the output level of a signal
source is too low to control a subsequent unit .
In this mode, the unit can also be used as
6-fold microphone preamplifier .
1) Disengage the selector button MIX/SPLIT
(7) for the respective channel and the se-
lector button MIXER ON (8) .

2) Use the selector buttons LINE / MIC (4) to
match the mono channels CH 1 to CH 6
to the connected sources . When a micro-
phone is connected, engage the selector
button; for units with line level, disengage
the button .
3) For the mono channels, adjust the desired
level with the controls LEVEL CH1 to CH6
(5) .
4) For the stereo channel, set the control
LEVEL STEREO OUT (9) to maximum and
use the controls LEVEL STEREO IN (3) to
adjust the desired level individually for the
left channel and the right channel .
6.4 Combined operating modes
If not all six mono channels are required as
outputs in the splitter mode, the remaining
channels can be operated as individual and
independent amplifiers . See chapter 6 .3 .
